What's the quickest way to put a stop to all those, "girl car" jokes when you've just dropped a pretty penny on your new SLK? Drop the 617bhp engine from an SLR McLaren into it. Duh. Along the way, it would be nice to cut holes in the hood to clear the massive engine and if you started with an SLK55 AMG (with its monobloc brakes and stiffer suspension), well, that would put an end to all the, "driving the wife's car today?" ribs from Greg in accounting. So who, or what, would shoehorn the engine from a $500,000 car into the engine bay of a $40,000 one? We found this account, re-posted to a Canadian online forum.

I was on my way home from school when I see an SLK wit two black patches on the hood. I was like "stickers". So I decided to check it out ... I get close and see that those black patches were actually the engine sticking out of the hood ... I was even more shocked when I read SLR on the engine. So I started snapping pics. When a Nissan Armada pulls up and who else but [rally driver] Bin Sulayem steps out of the house to get something from the Armada. Then he gets in the SLK and calls me to talk to him ... My first reaction was to point speechless at the hood. He told me got the engine and put it in himself and changed the transmission, and it's a RWD. He said it had 615hp, and could go well over 350 km/h. He told me he had already been up to 320. He said it's a one of a kind, and that AMG are coming to Dubai just to see it.
